eiaas Posted August 23, 2019 Share Posted August 23, 2019 Hi Problem with Dec motor on my Sky Watcher NEQ6 Pro. See video. https://youtu.be/3W4VezvZHTw Link to comment Share on other sites More sharing options...
Dr_Ju_ju Posted August 23, 2019 Share Posted August 23, 2019 I don't have one, but a few things to try, swap the RA & DEC cable connections, that will at least tell you if its the motor or driver board. is your voltage +13v DC and stable ? How old is the mount? is it just high speed are the slower speeds also playing up ?? Link to comment Share on other sites More sharing options...
eiaas Posted August 23, 2019 Author Share Posted August 23, 2019 The mount is old,pats are new. Ra motor as normal. New motherboard, new Dec motor, tested handcontrol ok, firmware new to handcontrol and mount. New cabels. New powertank. Have not tried to swap RA DEC cables. PS! Two different contacts. for RA / DEC motor. Link to comment Share on other sites More sharing options...
Dr_Ju_ju Posted August 23, 2019 Share Posted August 23, 2019 usually for Skywatcher the driver board, motor outputs, use the same type of connector, so you can swap them there (carefully not shorting anything). Link to comment Share on other sites More sharing options...
eiaas Posted August 23, 2019 Author Share Posted August 23, 2019 Not this one, DEC conector has a wider connetor than RA. Link to comment Share on other sites More sharing options...
Dr_Ju_ju Posted August 23, 2019 Share Posted August 23, 2019 How long have you had the problem with the DEC motor ?? especially if you've been changing almost everything ….. but to identify the problem part, the first thing I would do would be to drop out the hand controller, but this means driving the mount from a computer directly, are you able to do this ?

eiaas Posted August 23, 2019 Author Share Posted August 23, 2019 Have tried a new handcontroller, same problem. So I vent back to the old one. Might be the motherboard, since this is the third DEC motor I have tried, and everyone came up with the same problem. Link to comment Share on other sites More sharing options...
Dr_Ju_ju Posted August 23, 2019 Share Posted August 23, 2019 its either the motherboard or the cabling to the motor, if you've changed everything else..... Link to comment Share on other sites More sharing options...
eiaas Posted August 23, 2019 Author Share Posted August 23, 2019 New motherboard,new DEC motor,New Powertank from Sky Watcher,New power cable from First light Optics,New Syn Scan version 4 tested, same problem. 3 different DEC motors tested,same problem. Voltage to the motors ok, RA motor is ok,works fine. This is the second winter without the mount, been used manualy so far. Link to comment Share on other sites More sharing options...
1parsec Posted August 23, 2019 Share Posted August 23, 2019 How tight is the mesh between the motor pinon gear and the larger idler gear? There should be a very small amount of clearance. If they are meshed tight it could make the motor is stall. Link to comment Share on other sites More sharing options...
eiaas Posted August 23, 2019 Author Share Posted August 23, 2019 I have run the DEC motor with the biggest gear removed, and its the motor (standalone) who have the problem. Link to comment Share on other sites More sharing options...

eiaas Posted August 23, 2019 Author Share Posted August 23, 2019 A new motherboard "might" solve the problem. Link to comment Share on other sites More sharing options...
